New Designer Opioid Cychlorphine Raises Alarm In Oklahoma

Clinical Review by Matt Hawk, B.Sc., ADC (IC&RC), CAC II (ADACBGA)

Health experts are raising alarms over a new designer opioid that has proven resistant to Narcan, the medication commonly used to reverse opioid overdoses. First identified in Europe, the drug known as cychlorphine has since spread to Canada and the United States, where it is already being linked to fatal overdoses.

Cychlorphine is an opioid estimated to be ten times more potent than fentanyl, making it one of the most dangerous synthetic drugs to emerge in recent years. It is typically found mixed with other substances or pressed into counterfeit OxyContin or Xanax pills, and can also appear in powder or liquid form. Because it is so frequently disguised or combined with other drugs, many victims may have no idea they are ingesting it.

“We all really thought that fentanyl was a huge deal and that was really bad. Now, we have this deadly synthetic opioid that is way worse than fentanyl.”

The drug has now been confirmed in multiple regions across the country, including Oklahoma, where the first known fatal overdose claimed the life of an 18-year-old in the Oklahoma City area. Oklahoma Bureau of Narcotics spokesman Mark Woodward captured the gravity of the situation plainly: “We all really thought that fentanyl was a huge deal and that was really bad. Now, we have this deadly synthetic opioid that is way worse than fentanyl.”

Public health officials are urging communities, first responders, and harm reduction organizations to be aware that standard Narcan protocols may be insufficient against cychlorphine, and are calling for increased vigilance as the drug continues to spread across North America.

Cychlorphine’s Damaging Effects Felt Across the Country

In the U.S., cychlorphine was first detected in Florida in 2024. By the end of February 2026, the Drug Enforcement Administration had detected cychlorphine in 22 drug samples received by their lab.

Warnings about cychlorphine were quickly released in Kentucky, Ohio, Tennessee, and now Oklahoma. According to the Center for Forensic Science Research and Education (CFSRE), the drug has also been found in California, Nevada, New York, Pennsylvania, Texas, Louisiana, and Illinois, as well as in three provinces in Canada.

What makes cychlorphine even more dangerous than fentanyl is that it can require multiple doses of naloxone (Narcan) to reverse its effects. Also, it may not be able to be detected by test strips used by harm reduction advocates and drug users. Anyone who is addicted will simply be at the mercy of drug manufacturers and dealers.

A Constant Stream of New Synthetic Drugs

Since 2013, when fentanyl began to arrive in the U.S. in volume, American drug users have faced one synthetic opioid threat after another. Fentanyl was followed by acetylfentanyl and then ultra-potent carfentanil in 2016. More than 100 fentanyl variants had been detected by 2020.

Brorphine, similar to cychlorphine but less powerful, arrived on the illicit market in 2019. That was followed by several drugs of the nitazene class, another group of synthetic opioids detected in 2020. Cychlorphine is just the next one to arrive, but not the last.

For Synthetic Drugs, No End in Sight

With a chemist, a lab, and a few essential chemicals, an illicit lab can manufacture an endless variety of synthetic drugs. However, the vast majority of these products have never been subjected to standard pharmaceutical safety testing. To come up with a new drug, chemists can simply manipulate the molecules in the formula. The new substance may be deadly, not yet illegal because it’s brand new, and not even detectable with existing tests.

Woodward further commented that “It seems like almost every few days or weeks, we see a new synthetic drug hitting the streets. We've identified over a dozen different types of synthetic nitazines now and cychlorphine, which has already caused deaths in other states.”

Cychlorphine Precursors Likely Coming from Overseas

Like Fentanyl, the precursor chemicals used to manufacture the drug originate in China. The precursors are then shipped to other countries where they are manufactured. It's not clear how much of the manufacturing is done within the United States.

Timothy Wiegand, president-elect of the American Society of Addiction Medicine commented, “Most of these are coming from either South Asia, China, places where there’s a lot of chemical supply companies…It’s coming from international, multilevel drug distribution networks, some of the cartels or other isolated networks.”

Drug Prevention and Rehab Are Essential Parts of the Solution

Recent history has taught us that the drugs on the illicit drug market change faster than we can update our laws to ban them. As one drug gets outlawed, it’s replaced by a new one that could be even deadlier. For this reason, drug prevention and rehabilitation take on a whole new importance.

These days, the only safety for a person using illicit drugs is in a new sobriety. Every day a person spends addicted is a day they could lose their life. That’s why Narconon Arrowhead in Canadian, Oklahoma has been offering a long-term, residential rehab program since 2001. There must be hope for those who are addicted and for Oklahoma families.

Narconon Arrowhead Is Here to Help

 

We can provide free drug education lectures to local groups, including church youth groups, community centers, and scouting organizations. Our speakers understand the issues around drug abuse and can connect with young people.

Narconon will also provide free drug informational booklets and assist in distribution in the most vulnerable areas that are especially hard hit by drug abuse.

We love our home in Oklahoma—and appreciate the beautiful landscapes, the lakes, the rich Native American and cowboy heritage, but most of all—the people.

We agree with the Oklahoma Standard, the statewide initiative that promotes civic responsibility based on the core values of service, honor, and kindness.
